Nature-based solutions (NBS) have recently received attention due to their potential ability to sustainably reduce hydro-meteorological risks, providing co-benefits for both ecosystems and affected people. Therefore, pioneering research has dedicated efforts to optimize the design of NBS, to evaluate their wider co-benefits and to understand promoting and/or hampering governance conditions for the uptake of NBS. In this article, we aim to complement this research by conducting a comprehensive literature review of factors shaping people’s perceptions of NBS as a means to reduce hydro-meteorological risks. Based on 102 studies, we identified six topics shaping the current discussion in this field of research: (1) valuation of the co-benefits (including those related to ecosystems and society); (2) evaluation of risk reduction efficacy; (3) stakeholder participation; (4) socio-economic and location-specific conditions; (5) environmental attitude, and (6) uncertainty. Our analysis reveals that concerned empirical insights are diverse and even contradictory, they vary in the depth of the insights generated and are often not comparable for a lack of a sound theoretical-methodological grounding. We, therefore, propose a conceptual model outlining avenues for future research by indicating potential inter-linkages between constructs underlying perceptions of NBS to hydro-meteorological risks.

“…While hard-engineered watercourses remain widely trusted in Taiwan's dense, flood-prone urban areas [32], it is inevitable that local residents near the Laojie River worry about potential floods after culvert-removal, echoing a study by Tunstall et al [29]. People's flood-risk perception is real, and therefore understanding it and its roots is crucial when implementing river restoration projects.…”

“…An assessment checklist was then established based on a review of the literature on multi-functional urban river space design [3,14,32,51] (see Appendix A). Accessibility, diversity, enjoyment and sustainability, as the four key concepts for designing multi-functional urban rivers to achieve multiple recreational, social and environmental roles, formed the structure of the assessment checklist.…”

“…Nevertheless, in terms of managing rivers, the actual effect was limited since engineering solutions, e.g., cycleways, dominated riverside landscape facilities [45]. Additionally, the strategy of quasi-naturalistic landscaping design was gradually adopted for rehabilitating urban culverted rivers, e.g., the Mei Stream in the City of Taichung [32], where an upper-level man-made stream was created to provide recreational use and riverine environment, while the real stream remained underground to carry riparian rainwater and wastewater downstream. This double-layer stream layout is the subject of debate within urban river management.…”

“…The popularity of hard-engineered watercourses as well as the problems of wastewater contamination are issues in its densely-urbanized areas [32]. De-culverting the Laojie River in densely-urbanized Taoyuan City is a recent significant example of improving a river environment [33,34] that intends to transform a channelized, culverted, flood-control watercourse into a multi-functional resource by focusing on riverside landscape and water quality improvements [35].…”

A paradigm shift in river management practice is underway, from a hard engineering-dominated emphasis that endeavours to control water, to a multi-functionality-framed approach that strives to restore a river's ecology, scenery and ecosystem services. In Taiwan, the Laojie River in Taoyuan City, where a channelized and piped urban river was recently transformed into an accessible, linear green infrastructure feature, is widely regarded as the first extensive and successful river restoration project in Taiwan's densely-urbanized, flood-prone areas, yet its actual performance is rarely examined in any depth. Through in-depth interviews, fieldwork and a review of government documents, this paper presents findings on the practical factors involved in the practice of river restoration and their implications for urban river management. First, local people support river restoration with de-culverting, but potential flooding is a concern that results from different flood-risk perceptions and ineffective flood-risk communication between the government and public. Second, a mix of hard and soft edges to the watercourse improves the riverside landscapes in a densely-urban, flood-prone area. Third, due to a lack of basin-wide supporting sanitary sewer systems, a combination of on-site gravel contact oxidation treatment systems and riverside sewage-intercepting facilities still fails to improve the river water quality. Fourth, people's positive attitudes towards river restoration are largely associated with landscape aesthetics and recreational value, rather than water quality and biodiversity. It is revealed that using the Cheonggyecheon Stream in South Korea as a frame for river restoration seems effective in providing local people with an example of successful river restoration, based mainly on flood prevention and recreational and aesthetic improvement. Moreover, the effective flood-risk communication is mainly reliant on an intelligible presentation of related information to the general public. Practical, continuous and extensive public participation, with various types of involvement and resources along with a solid system of social objectives by which to assess the outcome, is central to the social aspect of river restoration.

A place‐based risk appraisal model for exploring residents’ attitudes toward nature‐based solutions to flood risks

et al. 2023

Nature‐based solutions (NBS) have gained popularity as a sustainable and effective way of dealing with increasing flood risks. One of the key factors that often hinders the successful implementation of NBS is residents’ opposition to their implementation. In this study, we argue that the place where a hazard exists should be considered a critical contextual factor alongside flood risk appraisals and perceptions of NBS themselves. We have developed a theoretical framework—the “Place‐based Risk Appraisal Model (PRAM)”—that draws on constructs inspired by theories of place and risk perception. A citizen survey (n = 304) was conducted in five municipalities in Saxony‐Anhalt, Germany, where dike relocation and floodplain restoration projects have been conducted along the Elbe River. Structural equation modeling was adopted to test the PRAM. Attitudes toward the projects were assessed in terms of “perceived risk‐reduction effectiveness” and “supportive attitude.” With regard to risk‐related constructs, well‐communicated information and perceived co‐benefits were consistently positive factors for both perceived risk‐reduction effectiveness and supportive attitude. Trust in local flood risk management was a positive and threat appraisal a negative predictor of perceived risk‐reduction effectiveness affecting “supportive attitude” only through “perceived risk‐reduction effectiveness.” Regarding place attachment constructs, place identity was a negative predictor of a supportive attitude. The study emphasizes that risk appraisal, pluralities of place contexts to each individual, and their relations are key for determining attitudes toward NBS. Understanding these influencing factors and their interrelationships enables us to provide theory‐ and evidence‐based recommendations for the effective realization of NBS.
